COMPGSITION 0F MATTER FOR USE AS A CEMENT.

E0 Drawing.

To all whom it may concern:

Be it known that I, HARRY A. Coon, a citizen of the United States, residing at Yakima, in the county of Yakima and State of WVashington, have invented a new and useful Composition of Matter for Use as a Cement, of which the following is a specification.

Pure rubber 8 pounds. A rubber solvent (benzol) 10 gallons.

(Iround white shellac 7, pound. Alcohol (180 proof) 6 pints. Powdered white rosin 1 pound. Oil of Sassafras 8 ounces. :llther 8 ounces.

In making the adhesive cement the rubher is cut into small squares and put in a container with substantially 10 gallons of benzol or with enough benzol to make substantially 10 gallons of the mixture. This mixture is stirred continuously until the Application filed March 21, 1921. Serial No. 454,138.

rubber is dissolved. One quarter pound of ground white shellac in a dry state is added to 3 pints of alcohol and dissolved therein. In another container 1 pound of powdered white rosin is dissolved in 3 pints of alcohol. These two solutions of shellac and rosin are then mixed together thoroughly by stirring in with the rubber solution after which the oil of Sassafras and the ether are added and the entireinixture is stirred for one-half an hour. It is then ready to be canned and used.

What is claimed is A composition of matter for use as an adhesive cement including a solution of pure rubber in benzol in the proportions of eight pounds of rubber to suflicieut benzol to make approximately ten gallons, a solution of one quarter pound of ground white shellac in three pints of alcohol, a solution of powdered white rosin in three pints of alcohol, said solutions being thoroughly mixed with eight ounces of oil of Sassafras and eight ounces of ether.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

HARRY ANDY COOK.
